I have a 4+ year old Dell Inspiron 9300 notebook running Windows XP Home Edition, as well as Slackware Linux in a dual boot configuration. I have SpeedStep enabled in the BIOS and in Linux the CPU speed would fluctuate depending on what I was doing. If I were to compile a program the CPU speed would go from 800MHz to 1.86GHz and then slowly climb back down once the compiling was done. This is how it should behave, but it no longer does! Now when I compile a program it stays at 800MHz, however the fan will kick up as if the CPU was getting excited. Booting into Windows used to also kick up the fan, which told me the CPU was revving up as well, but now it does not do that either. Running the RightMark CPU Clock Utility (RMClock) under Windows I'm told the speed is around 800MHz, as well as the utilities in Linux. Weird thing is the info under System Properties General Tab tell me it's running at 1.86GHz... BIOS tells me the min is 800MHz and max is 1.86GHz and once in a while it will actually say the speed is at 1.86GHz, but then it drops to 800MHz. I guess that latter part is usual since there's nothing CPU intensive while in the BIOS... anyone have any suggestions?
